Minecraft Obby

The core loop is deceptively simple: jump from block to block without falling into the void. You're using WASD or arrow keys to move, space to jump, and that's it for controls. But the game throws a lot at you across its 50+ levels. Early on, you get easy platforms like in Green Hills -- just wide stone blocks with a few gaps. You'll feel like a parkour pro. Then around world three, things shift. Lava Cavern introduces moving platforms that sink when you stand on them too long, and Spiders Nest' has those sticky web blocks that slow your jump arc. Your brain has to switch from pure timing to spatial awareness. Coins are scattered on risky paths -- some float midair off the main route, others sit on pressure plates that trigger falling spikes. Collecting them is optional but matters if you want the good swords. The shop has about eight swords: the Wooden Blade is free, but the Diamond Saber (costs 150 coins) gives you a double-jump ability for three seconds after each landing, which is huge for the later ice-block levels. Enemies show up around level 15 -- Zombie Alley has slow shamblers you can jump over, but Blaze Fortress has fireballs on timers. You learn to read the patterns. The satisfying moments come from nailing a long chain of jumps without pausing -- like in Sky Bridge, where you have to sprint-jump across narrow pillars while avoiding creeper heads that drop from above. Failing is fast, so you respawn instantly at the last checkpoint flag. Each world has a boss level: The Ender Dragons Lair' is a gauntlet of collapsing blocks where you have to keep moving upward. The difficulty scales by mixing mechanics -- one level might combine moving platforms with arrow traps and a timed gate. What's nice is the game doesn't explain much. You figure out that holding shift crouches for precise edges, or that double-tapping a direction gives a short dash, but none of this is in the tutorial. The music loops and gets more intense as you progress, which adds pressure. Coins also unlock particle trails (fire, water, void) for your character, but that's cosmetic only. There's no story, just the constant threat of falling into red-and-black nothingness. Some levels, like Piston Panic, rely on pistons pushing you forward at set intervals, so your jump timing has to sync with the block movement. Then Obsidian Maze has invisible walls you learn by dying. You'll die a lot. Each death costs you a few coins if you're carrying any, which makes saving up for that Diamond Saber a grind. But the checkpoint system is generous -- every five platforms saves your progress, so you never lose more than a short run.
